Step Types
Prowl supports 28 step types. Most have both a shorthand form (concise, readable) and an explicit form (full control over selectors).
navigate
Navigate to a URL (relative to your target.url or absolute).
- navigate: "/"
- navigate: "/login"
- navigate: "https://example.com/page"
click
Click an element. Shorthand finds buttons by text, then falls back to any matching text.
- Shorthand
- Explicit
# Finds by button role, then text
- click: "Sign In"
# Use any Playwright selector
- click:
selector: "[data-testid='submit-btn']"
Shorthand click uses substring matching on button names. click: "Save" will match a button labeled "Save & New". For exact matching, use click: { selector: 'button:text-is("Save")' }.
fill
Fill an input field. Shorthand finds inputs by label or placeholder text.
- Shorthand
- Explicit
# Finds by label, then placeholder
- fill:
"Email": "user@example.com"
# Use any selector
- fill:
selector: "input[name='email']"
value: "user@example.com"
type
Type into the currently focused element. Useful after clicking into a field.
- Shorthand
- Explicit (fill equivalent)
- click: "Message"
- type: "Hello, I have a question."
- fill:
selector: ":focus"
value: "Hello, I have a question."
copyText
Extract the text content of an element and store it as a runtime variable for use in later steps. Explicit-only.
selector(required) — element to read text fromas(required) — variable name to capture the text into
- copyText:
selector: "[data-testid='order-id']"
as: "ORDER_ID"
- navigate: "/orders/{{ORDER_ID}}"
press
Press a keyboard key on a specific element.
- press:
selector: "input[name='search']"
key: "Enter"
select / selectOption
Select a dropdown value. Shorthand finds by label, explicit uses a selector.
- Shorthand
- Explicit
# Finds <select> by label, aria-label, or placeholder
- select:
"State": "FL"
- selectOption:
selector: "select[name='state']"
value: "FL"
assert
Mid-flow assertions. Fails the hunt immediately if the assertion fails.
- assert:
visible: "Welcome back"
- assert:
notVisible: "Error"
- assert:
urlIncludes: "/dashboard"
- assert:
urlEquals: "https://example.com/dashboard"
See the Assertions page for the full reference.
wait
Wait for text to appear on the page.
- Shorthand
- Explicit
# Wait for text with default timeout
- wait: "Loading complete"
# With custom timeout
- wait:
for: "Loading complete"
timeout: 10000
wait uses exact text matching (text="X"). It won't match substrings. For substring matching, use waitForSelector with text=X (without quotes).
waitForSelector
Wait for any Playwright selector to appear.
- waitForSelector:
selector: "[data-testid='results-table']"
timeout: 5000
waitForUrl
Wait for the URL to contain a substring.
- waitForUrl:
value: "/dashboard"
timeout: 10000
waitForNetworkIdle
Wait for all network requests to complete.
- waitForNetworkIdle:
timeout: 5000
waitForDownload
Wait for a file download to start and save it into the run's artifact directory. Explicit-only; pass null to accept any download. Author it immediately after the step that triggers the download.
filename(optional) — assert the downloaded file's name; the step fails if it doesn't matchtimeout(optional, default30000) — max time to wait, in ms
# Assert the filename
- click: "Export CSV"
- waitForDownload:
filename: "report.csv"
# Accept any download
- click: "Download"
- waitForDownload: null
The downloaded file is saved into the run directory (.prowl/runs/<timestamp>/).
onDialog
Handle browser-native dialogs (alert, confirm, prompt). Register the handler before the action that triggers the dialog.
- onDialog:
action: accept # or "dismiss"
- click: "Delete" # this triggers the confirm dialog
setInputFiles
Set files on <input type="file"> elements. Paths are relative to .prowl/.
# Single file
- setInputFiles:
selector: "[data-testid='avatar-upload']"
files: "fixtures/avatar.png"
# Multiple files
- setInputFiles:
selector: "[data-testid='attachments']"
files:
- "fixtures/doc1.pdf"
- "fixtures/doc2.pdf"
runHunt
Execute another hunt file inline. Enables reusable sub-flows like login.
- Shorthand
- Explicit
# Run the hunt as-is
- runHunt: "login-flow"
# With variable overrides
- runHunt:
name: "login-flow"
vars:
EMAIL: "admin@test.com"
PASSWORD: "{{ADMIN_PASSWORD}}"
Circular dependencies are detected automatically (A → B → A will error).
if
Conditionally run steps based on whether a selector is visible. Explicit-only.
visibleornotVisible(exactly one) — the selector to testthen(required) — steps to run when the condition holdselse(optional) — steps to run otherwise
- if:
visible: ".cookie-banner"
then:
- click: ".accept"
else:
- wait: "Welcome back"
repeat
Repeat a block of steps a fixed number of times or while a selector condition holds. Explicit-only. The maxSteps guardrail is enforced across all iterations.
times(fixed count) orwhile(condition) — exactly onewhile.visible/while.notVisible— the condition, when usingwhilemaxIterations(required withwhile) — safety cap on loop countsteps(required) — steps to run each iteration
# Fixed count
- repeat:
times: 3
steps:
- click: ".load-more"
# Condition-based loop
- repeat:
while:
visible: ".load-more"
maxIterations: 10
steps:
- click: ".load-more"
mockRoute
Intercept a URL pattern and return a custom response — useful for testing error, loading, or empty states. Explicit-only.
url(required) — Playwright route pattern (e.g.**/api/users)response.status(required)- exactly one of
response.bodyorresponse.file response.contentType(optional, defaultapplication/json)
- mockRoute:
url: "**/api/users"
response:
status: 200
body: '{"users":[{"id":1}]}'
unmockRoute
Remove a previously registered route mock. Explicit-only.
url(required) — must match the mocked route's pattern
- unmockRoute:
url: "**/api/users"
evalScript
Evaluate a JavaScript expression in the browser page context, optionally capturing the result as a runtime variable.
- Shorthand
- Explicit (capture result)
# Evaluate without capturing
- evalScript: "window.scrollTo(0, 0)"
- evalScript:
expression: "document.querySelectorAll('tr').length"
as: "ROW_COUNT"
- assert:
visible: "{{ROW_COUNT}} results"
The captured result is stringified and available as {{ROW_COUNT}} in later steps.
runScript
Execute an external JavaScript file in the browser page context. Explicit-only.
file(required) — path to the script; absolute, or relative to the config directory (.prowl/)
- runScript:
file: "scripts/seed-data.js"
assertScreenshot
Visual regression check: compare the current screenshot against a stored baseline. Explicit-only.
name(required) — baseline identifier; stored at.prowl/baselines/<name>.pngthreshold(optional, default0.1) — allowed pixel-difference fraction (0–1)
- assertScreenshot:
name: "homepage"
- assertScreenshot:
name: "checkout-form"
threshold: 0.05
On the first run the baseline is created and the step passes. On later runs the current screenshot is compared against the baseline; the step fails if the difference exceeds threshold, writing a diff image into the run directory. Accept new baselines with prowl update-baselines.
screenshot
Capture a screenshot at any point.
- screenshot:
name: "after-login"
hover
Hover over an element. Useful for triggering tooltips, dropdown menus, or hover states. Explicit-only — requires a selector.
- hover:
selector: "[data-testid='user-menu']"
- hover:
selector: "text=Profile"
scroll
Scroll the page by direction and optional pixel amount.
# Scroll down (default amount)
- scroll:
direction: "down"
# Scroll up by 300px
- scroll:
direction: "up"
amount: 300
scrollTo
Scroll to a specific element on the page. Explicit-only — requires a selector.
- scrollTo:
selector: "[data-testid='pricing-section']"
- scrollTo:
selector: "text=Footer"
